Liquid noble gases for dark matter searches: An updated survey

Abstract

An updated technical and methodological comparison of liquid noble gas experiments is presented with particular attention to the low energy physics application of double-phase noble gas detectors in direct Dark Matter investigations.

Candidates of Dark Matter

“…The XENON100 experiment has released data for an exposure of 224.6 days, using a fiducial volume of just 34 kg of Xenon target mass [26]. See related discussions in literature about the detector response of such devices, in particular, to low energy recoils [27,28]. The technical performance of the apparata, confirmed also by similar experiments, has shown e.g.…”

“…[18,27,28,39,44]). However, often some critical points exist in their experimental aspects, as mentioned above, and the existing experimental and theoretical uncertainties are generally not considered in their presented single model dependent result; moreover, implications of the DAMA results are often presented in incorrect/partial/unupdated way.…”

Results and strategies in dark matter detection

“…The XENON100 experiment has released data taken in the years 2011-2012 for an exposure of 224.6 days, using a fiducial volume of just 34 kg of Xenon target mass 35 . See related discussions in literature about the detector response of such devices, in particular, to low energy recoils 17,18,36 . The technical performance of the apparata, confirmed also by similar experiments, has shown, e.g.…”

“…Similar considerations, as above, hold about the robustness of these results. Moreover, such considerations become still more restrictive when considering the future plans of larger set-ups 17,18 . A positive hint for a signal of light DM candidates inducing just nuclear elastic scatterings has been also reported by the CoGeNT experiment 40,41 .…”

Highlights on signals from Dark Matter particles

“…Some activities claim model-dependent exclusion under many largely arbitrary assumptions (see for example discussions in Ref. [10,11,15,[40][41][42]). Moreover, often some critical points exist in their experimental aspects, as mentioned above, and the existing experimental and theoretical uncertainties are generally not considered in their presented single model dependent result; moreover, implications of the DAMA results are often presented in incorrect/partial/unupdated way.…”
